军用飞机空中发射或地面发射的导弹,一般都是由雷达传感器、红外传感器或这两种传感器的结合体制导的。雷达传感器在目标识别和定位方面非常准确,缺点是其发射容易被目标发现。红外传感器是被动式的,其存在或操作不会被发现,但视场通常相当窄。因此,必须在发射导弹之前获取潜在的目标,并在从发射到截击的整个时间 Missile missiles, which are airborne or ground-launched by military aircraft, are generally guided by radar sensors, infrared sensors or a combination of both. Radar sensors are very accurate in identifying and locating targets, but have the disadvantage that their emissions can be easily detected by the target. Infrared sensors are passive, their presence or operation can not be found, but the field of view is usually quite narrow. Therefore, potential targets must be captured before the missiles are launched and, throughout the entire time from launch to interception
